Figure 6

Data evolution along time for random radial distances in a control example. In red is shown the fitted exponential function. The measured distances are: a) 2 pixels, b) 23 pixels, c) 58 pixels and d) 95 pixels. The vertical axis shows relative calcium concentration (same scaling all the samples) and horizontal axis is the normalized time (0 is the beginning of acquisition, and 1 the end of acquisition).
